<p>A system for detecting misalignment of an aero surface (11a) relative to other aero surfaces (lib- lid) during simultaneous deployment of said aero surfaces is disclosed. It comprises a generator (16) configured to shine a laser (15) through aligned apertures (13) in a series of aero surfaces towards a reflector (17) during deployment of said aero surfaces, a receptor to detect reflection of said laser (15) from said reflector (17) back through said apertures (13) to the generator (16) and, a controller operable to terminate further deployment of said aero surfaces in the event that no reflection is detected by said receptor, or if an actual time taken for the reflected beam of light to be detected by the receptor differs from a predetermined time. In a preferred embodiment the aero surfaces are slats (11a- 11d) extending from the leading edge of an aircraft wing (10).</p> |
